To all whom if may concern:

Be it known that l, Grnoiionv W. Rioirsr'rs, citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvanla, have invented certain new and useful Improvements1 n Nindlndicatoraof which the following 1S a specification,.referencebeing' had to the accompanying drawings.

My invention relates to new and useful improvements in the art ofmeasuring instruments and more particularly to a device known as a windindicator, and my object is to provide a device of this character whichmay be readily used on both sea and land for indicating to those withina housing the direction in which the wind is blowing.

A. further object of the invention resides in the provision of asubstantial compass mechanism in connection with a weather vane, and astill further object resides in providing a disk such as is used incompasses and mountingl the same on the lower end of the rod carryingthe weather vane, whereby said disk will be rotated with the rotation ofthe vane.

A further object of the invention resides in the provision of a devicewhich is eX- tremely simple and durable in construction, inexpensive tomanufacture, and one which will be very efficient and useful inoperation.

With these and other objects in view, my invention consists in the novelfeatures of construction, combination and arrangement of parts as willlbe hereinafter referred to :and more particularly pointed out in thespecification and claims.

ln the accompanying drawing forming a part of this application, Figure 1is a vertical section through the device, and, Fig. 2 is a horizontalsection therethrough as seen on line 2-2, Fig. 1.

In lcarrying,- out my invention, I shall refer to the drawing in whichsimilar reference characters designate correspondingn parts throughoutthe several views and in which- 1 indicates a circular base member ofany desired size, whatsoever, having a threaded portion 2 thereon, andengaged with the threaded portion, is the lower threaded portion of acylindrical housing or casing 3 which is preferably formed of glass. Ex-

tending vertically from the center of the top face o the base 1, is astub shaft or spindle 4 which has the upper portion thereof reducedconsiderably to form a stem 5, the purpose of which will be hereinafterand more particularly described, and an additional cylindrical' casingor housing G has a central opening 7 in the bottom thereof whlchreceives therethrough, the stem 5, said opening being of such size as topermit the casing 6 to rest upon the shoulder formed between the sternand the main portion of said shaft et. This casing or housing 6 is alsopreferably formed of glass having,- a removable top 8 thereon, which toprests ou an annular shoulder 9 formed on the inner face of the wall ofsaid casing adjacent the upper edge thereof. This top 8 is adapted to besecurely held in position on the shoulder 9 by means of a spring wireinember 10 which is engaged with the top to spring tightly against theinner face of the reduced portion of the side walls of said casing orhousing 6.

Mounted on the bottom of the casing or housing." 6, is a dial 11 havingthe various points of the compass marked thereon, such' as North, EastfSouth, West and the intermediate points, said dial being also providedwith a central opening in alinement with the opening 7 in the bottom ofthe casing` 6 to permit the stem 5 to pass therethrough, and a compassneedle l2 of the usual or any preferred type is disposed within saidcasing 6, said compass needle having; the usual central socket 13therein which receives the free end of the stem 5.

IThe needle is so positioned as to be spaced a slight distance above theupper face of the dial, whereby it will be appreciated that the casing 6may be revolved on its axis independently of the needle, which normallypoints northward, and a shaft 14 which is rotatably disposed through acentral opening in the top of the casing 3, has the lower end thereofwhich extends within said casing, squared, as shown at 15, and extendedthrough a central square opening in the top 8 of the casing 6. Washers16 are positioned on the squared portion 15 of the shaft: above andbelow the to and anut 17 en aged with the extreme ower end of the sha t14,

is turned into engagement wit-h one of the washers to securely retainthe top 8 to said shaft, whereby it will be appreciated that said casing6 may be properly supported in the casing 3 and designed to rotatetherewithin upon the rotation of the shaft. This shaft 14 may be of anydesired length, whatsoever, and removably mounted on the upper endthereof, is a weathervane 18 designed in the form of an arrow, as usual,and in positioning said vane upon the shaft, the head thereof i directedto point to the North point indicated on the dial 11. The East and Westpoints and their respective intermediate points are positioned on thedial reversely to the actual positions of the same with respect to theNorth and f South points, and thus when the vane 18 is turned in thedirection in which the wind is blowing, the dial which will obviously beturned therewith, will dispose a point thereon in position below orimmediately adjacent the point of the needle 12 to indicate t-he exactdirection from which the wind is blowing, it being understood that saidneedle 12 always points to the north.

In ractice, the base portion of the device is adapted to be disposed ina housing and the shaft 14 extended through the roof thereof to permitthe vane at the upper end thereof to be divdevice will, of course,

rected by the wind. If used on ships, to which the same is particularlyadapted, this be positioned in the pilot-house, and it will beappreciated that as the wind blows to turn the vane 18, the casing orhousing 6 with the dial in the bottom thereof, will correspondingly beturned to allow the points from which the wind is blowing, to bedisposed below the needle 12 which normally pointsnorthward. Thisdevice, therefore, may be used as a combined mariners compass and windindicator, thereby simplifying the usual construction for the twodevices mentioned.

From the foregoing, it will be seen that I have provided an extremelysimple, inexpensive and efficient device for carrying out the objects ofthe invention, and while I have particularly described the elements mostwell adapted to perform the functions set forth, it is obvious thatvarious changes in form, proportion and in the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the principles of the invention.

What I claim is :---y

2. A wind indicator, comprising a casing, an additional casing revolublymounted t-herewithin, a dial carried in the bottom of said lattercasing, a needle disposed within the last mentioned casing and mountedon the axis thereof over said dial, a weather vane, and connecting meansbetween said vane and additional casing to move the latter with themovements of the former.
